Justification
This species has a limited distribution range and has an extent of occurrence (EOO) of 6 479² km and an area of occupancy (AOO) of 100 km². It is known from 13 locations and the population is declining due to illegal collection to supply the succulent trade. It therefore qualifies as Near Threatened under criterion B.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape
Range
This dwarf succulent species is a South African endemic that occurs in Steinkopf and extends from Bushmanland to the Kamiesberg in the Northern Cape Province.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Kamiesberg Mountains Shrubland, Kamiesberg Granite Fynbos
Description
It grows on crevices in quartz-bearing rocks, either granite or gneiss.
Threats
The population is declining rapidly as a result of illegal collection, with over 191 plants included in confiscations between March 2019 and December 2021. Many more are likely to have been removed from the wild but not intercepted by law enforcement efforts. More than 3000 plants exported by a South African nursery during 2011-2018 are suspected to have been wild-sourced.
Population

It is fairly common in suitable habitat across its range, but the population is decreasing due to illegal harvesting to supply the succulent trade.
